[citat]Connecting a 555, or anything else for that matter, while a circuit is on will create a spike, that might cause instability. But I suppose you mean long term instability, the toy crashing without you doing anything at all?
One thing that might work is to put a capacitor (An electrolytic will do) of some pretty small value between the power supply pins, especially if not present in the circuit already. 0.1 uF should do the trick, but up to 1 uF or even higher won't hurt.
